RFR: 8378746: jdk/jfr/event/gc/detailed/TestZRelocationSetGroupEvent.java intermittent OOME

[SendaoYan]

Hi all,

Test jdk/jfr/event/gc/detailed/TestZRelocationSetGroupEvent.java intermittent fails "java.lang.OutOfMemoryError: Java heap space", the stack trace shows that there is no enough heap memory to finish  jfr event record sometimes on some specific machine. Should we increase the max heap memory to make test more robustness.

Additional testing:

- [x] Run thist test 10k times after the proposed patch.
